World Alzheimer’s Day: Over-reliance on technology puts brain health at risk, warn doctors

New Delhi: With artificial intelligence (AI) and digital tools now woven into daily life, doctors are cautioning against the growing dependence on technology for even the simplest tasks. While these tools support efficiency, overuse suppresses natural brain activity and limits imagination.

Alzheimer’s is a progressive neurological condition and one of the most common causes of dementia. Traditionally seen in people in their 60s, it is increasingly being detected earlier as awareness grows and individuals seek medical advice instead of dismissing symptoms as signs of ageing. Doctors emphasise that dementia is not a natural part of ageing but a serious condition that requires prevention and timely intervention.

Dr Sucheta Mudgerikar, Senior Consultant Neurologist, Apollo Hospitals, Ahmedabad, said, “The brain remains active and resilient when faced with regular challenges. Activities like puzzles, outdoor sports, or learning new skills keep brain cells alive and functional. But today, people are more attached to screens than real-world interactions. Even while travelling, they prefer watching phones instead of engaging with their surroundings. Technology should support thinking, not replace it. Over-dependence weakens imagination and cognitive strength, which directly impacts long-term brain health.”

Everyday practices also reflect this shift. Dr Devashish Vyas, Interventional Neurologist, Apollo Hospitals, Ahmedabad explained, “Earlier, people remembered routes, phone numbers, or task lists on their own. These habits kept the brain active. Today, navigation apps, reminders, and digital lists have replaced natural recall, reducing opportunities for mental exercise. What used to sharpen memory is now outsourced to devices.”

According to doctors, early warning signs of Alzheimer’s include forgetfulness such as struggling to recall recent meals, losing track of objects, losing track of familiar routes, or difficulty making decisions. As the disease progresses, the patients become more dependent.

Doctors urge families to watch children’s screen time as well. Instead of watching TV, mobiles or computers, playing problem-solving games together helps strengthen cognitive skills for both children and adults.

A healthy diet rich in fruits and vegetables, physical activity, and adequate rest are often overlooked but remain essential to brain function. Vitamin B12, in particular, is vital for nerve health. In Gujarat, where vegetarian diet limits natural sources of Vitamin B12, supplementation and awareness are necessary to prevent deficiencies that could worse memory and brain function.

“From late 40s, conscious efforts to remain mentally and physically active become even more important. Learning a new language, pursuing a hobby, playing games, can improve brain resilience. Alongside these efforts, avoiding sedentary habits is key, as physical fitness supports cognitive health”, said Dr Mudgerikar.

On World Alzheimer’s Day, Dr Devashish Vyas urges people to reflect on how technology shapes daily routines. Reducing dependency on devices for basic tasks, encouraging brain-stimulating activities at home, and helping the elderly stay engaged can significantly support brain health. Ultimately, protecting the mind means balancing the benefits of technology with the irreplaceable value of natural cognitive activity.
